RUECK table not clearing

Hello All,

I sincerely hope you can provide some insight, we are experiencing a production issue which is quite bothersome.

This is the scenario and problem description:

We have an external system which sends data via IDOCs in order to create confirmations for production orders. External system is functioning properly, all IDOCs are in great shape. However, table RUECK seems to be growing (where, as you know, it is supposed to be processed and contain 0 records). The only way to clear it is to manually process confirmations via CO16N.

We do have a job running every 5 minutes - SAPVBKK2. This job calls tcode CIP2, which calls func. module PROCESS_CC2_MESSAGES_PARALLEL. Even though this job is running, it is not picking up any records, and it is not clearing up RUECK.

The system change that was introduced prior to this issue is a master data change for work centers. On a costing tab of the work center master, new activity types and formula keys were introduced. Additionally, routing records were populated in User-Specific Fields - table PLPOD-USR04.

Your help is sincerely appreciated, and we look forward to your valuable advice.
